With a little experience/practice masking or use a piece of cardboard to protect areas you don’t want glue is quite fast.

One of the great thing about the spraying with he canisters is you never have to clean the gun, the hose or anything other than wiping the tip of the gun occasionally. Once you hook the hose to the canister and pressurize it you never turn it off until you change to another canister. The canisters can sit around for month at a time not being used and are ready to go when you are. Great system.
